基于正摄航拍影像的模型测图法应用分析

Application Analysis of Model Mapping Method Based on Positive Aerial Images

针对无人机航空摄影测量立体测图和基于倾斜模型三维测图的优势和不足,提出基于正摄航拍影像的模型测图法,并对正摄航拍影像航向、旁向重叠度进行了试验分析。工程实践证明,该技术路线可行,地形图精度满足相应规范精度要求,实用性较强。

Aiming at the advantages and disadvantages of UAV aerial photogrammetry stereo mapping and tilt model based three-dimensional mapping,this paper presents a model mapping method based on positive erial images,and carries out experimental analysis on the course and side overlap degree of forward aerial photography image.Engineering practice has proved that the technical route is feasible,the accuracy of topographic maps meets the requirements of the corresponding specifications,and the practicability is strong.
